Inverter ?

Our 2015 Winne inverter must be turned manually. We can leave it on and power our fridge on electricity rather than gas but that's not a really heavy gas user. Depending on the size of inverter, everyone's use is probably different. I have not seen one that turns on automatically. The current scheme I've seen with newer RVs is that they default to installing one big enough for a residential fridge whether or not the RV has one. I suspect they do that to salvage sales that might not happen if the buyer wanted a residential instead of gas. Easier to swap the fridges out. We improved the functionality of ours by replacing the 2 12 volt "deep cycles" with 2 golf cart batteries. That let us use our microwave easily at lunch stops without firing up the generator and watch TV as long as we want at night when at dry camping locations.
